Introduction

The game is an HD collection that features both Dragon Ball Z: Budokai 1 and Dragon Ball Z: Budokai 3 enhanced and re-mastered in HD, alongside full Trophy and Achievements support. The graphics of Budokai 3 HD are similar to those of Dragon Ball Z: W Bakuretsu Impact. Since the original soundtracks were composed by Kenji Yamamoto whose tracks have been accused of plagiarism, both included games have entirely new soundtracks and old soundtracks from Budokai Tenkaichi 2, 3, Tenkaichi Tag Team, and Ultimate Tenkaichi. Both games also sport the optional original Japanese language track.

Story related and can't be missed. This fight starts you off with yellow health vs Cell with green health. The fight can get pretty hard. The Easiest way I found was to guard and right after he completes his combo, use Kamehameha (PPPP->E). Repeat.

After you've completed the main storyline, this chapter will be available for selection.

Budokai Novice Champion 10
You won World Tournament mode on Novice in Dragon Ball Z: Budokai

From the main menu, go to World Match. Novice has 3 rounds and is fairly easy and has a 10 000 Zenie reward.Please refer to Budokai Advanced Champion for an easy victory strategy.

Budokai Adept Champion 20
You won World Tournament mode on Adept in Dragon Ball Z: Budokai

Can be bought from the Capsule shop after completing the Novice Championship. From the main menu, go to World Match. Adept can be challenging. It's 4 rounds a bit difficult and has a 30 000 Zenie reward. Please refer to Budokai Advanced Champion for an easy victory strategy.

Budokai Advanced Champion 50
You won World Tournament mode on Advanced in Dragon Ball Z: Budokai

Can be bought from the Capsule shop after completing the Adept Championship. From the main menu, go to World Match. Advanced can be very challenging as enemies will try and go for the ring out if you get careless. Advanced has 5 rounds and a 50 000 Zenie reward.Easy Strategy: choose a custom character to your liking (preferably a small character like Gohan or Krillen. Next equip Viral Heart disease and Vaccine. I personally didn't have vaccine, so I swapped it with a Senzu Bean capsule so that when I died, I would get a free revival with full health. This made it a cakewalk, obviously.

You gain Uub by killing Kid Buu in Goku's DU by a spirit bomb in his normal state. Your ultimate attack needs to be a success for the right cutscene to unlock.NOTE: This is best done in your second playthrough of DU

1) Finish Goku's DU story mode.
2) Start Goku's DU again and get to the Majin Saga.
3) Play until Gohan is absorbed by Super Buu and you're looking for someone to fuse with.
4) Find the ??? mark that starts the conversation with Hercule.
5) Talk to Hercule, then head towards the red dot on your map.
6) Don't battle Super Buu yet! Find the other ??? nearby and use it to talk to Tien.
7) Now search for the "Mountains" location.
8) If you've found the right area, you'll talk to Kabitoshin about how he's scared.
9) Now fight Super Buu.
10) Now a new red dot will appear and Vegeta will hold off Buu so you can check it out.
11) The red dot is Broly. Defeat him to unlock him.

The Advanced tournament has 5 rounds and can be purchased from the shop after completing the Adept tournament.
You'll need atleast 32 characters that are playable for this to appear in the Shop. Advanced isn't that bad. The AI handles kick ringouts (-> KKKK) pretty bad.
If that doesn't work, SSJ4 Goku with kamehameha spam does the trick too. full combo dealing around 800 dmg.
ALSO: When the AI goes into Hyper Mode, Always sway and side-dodge so he can't hit you. You don't want to be Dragon Rushed contantly.

Budokai 3 Cell Games Champion 40
You won the Cell Games in Dragon Ball Z: Budokai 3

The Cell Games have 5 rounds and you unlock it in the Dragon Arena. Cell broke in for me when I was using a lvl 23 Teen Gohan against lvl 52 Trunks.
Please refer to 'Budokai 3 Dragon Arena' for more information.

The Dragon Arena is an 'arena' in which you can fight enemies which get progressively stronger.
It automatically unlocks after completing Dragon Universe with all 11 characters.
Certain characters will also "break in", meaning that instead of the opponent you chose, you'll have to fight them. You get a nice reward if you beat them. Below you'll find some information about the people who break in and what their requirements are.(Ones in red are needed for an achievement)

Hercule: During Piccolo's second playthrough of DU, instead of fighting Buu, go to the Desert, near Baba's place you'lll find Hercule. Next, go to Central City and talk to Videl. When the conversation is finished, you'll have unlocked Hercule.

Videl: During Gohan's DU, search the lower right fields. (Near the World Tournament).

Uub: During Goku's second playthrough of DU, finish Kid Buu with a Spirit Bomb while in Normal State. If you did it correctly, the story will continue and you'll unlock Uub.

Saibamen: Unlocked in the Dragon Arena, Nappa must break in. You will need a level 10-20 character and battle opponents that are at least twice your level. I it did against a lvl 32 Videl with a level 15 Teen Gohan.

Android 16: On Krillen's DU, after fighting Frieza the first time two markers will appear. Go to the right one to talk to the Ginyu frog. Then continue the story and you will get to the Android saga. Search the islands east of the World Marial Arts Tournament and you will find a broken 16. Take him to West City and you will unlock him.

Android 17: Defeat Android 17 in Piccolo's DU.

Android 18: Finish Krillen's DU.

Dr. Gero: Defeat Dr. Gero in Yamcha's DU.

Cell: Defeat Cell in Teen Gohans DU.

Cell Jr: Unlocked in Dragon Arena, Piccolo must break in. You will need a 30+ character.
I personally got it with a lvl 37 Goku against a lvl 66 Tien.

Supreme Kai: In Adult Gohan's DU, you have to be in the second DU run and at the beginning when the red dot says Babidis Spaceship you have to go the mountains to talk to vegeta. Right before the final battle, search around in the 'Plain' area' to unlock Supreme Kai.

Bardock: In Goku's second playthrough of DU, check the Saiyan space pod in north-eastern area to unlock Bardock.

Cooler: Must finish Goku and Vegeta atleast once. In Goku's second playthrough of DU, defeat Frieza. 3 dots will appear on the map, take the bottom one to fight SSJ Vegeta, after you've defeated him, Cooler will appear. Defeat him to unlock him.

Broly:
1) Finish Goku's DU story mode.
2) Start Goku's DU again and get to the Majin Saga.

5) Talk to Hercule, then head towards the red dot on your map.
6) Don't battle Super Buu yet! Find the other ??? nearby and use it to talk to Tien.
7) Now search for the "Mountains" location.
8) If you've found the right area, you'll talk to Kabitoshin about how he's scared.
9) Now fight Super Buu. Make sure you kick his butt.
10) Now a new red dot will appear and Vegeta will hold off Buu so you can check it out.
11) The red dot is Broly. Defeat him to unlock him.

Omega Shenron:
1) Be on Goku's second playthrough of DU.
2) Get Goku's SSJ4 capsule, it's on one of the islands near the World Tournament.
3) Follow the same steps as for unlocking Broly.
4) Once you defeated Broly, ignore the red dot on the map and go to West City to Bulma.

6) Omega Shenron will now appear.
7) Defeat/rape Omega Shenron as SSJ4 Gogeta.

What is highlighted below in red are the things that I 'fixed' because they weren't typos but for example I wrote 1000, which what I did was add the : gsicon: and it will show the icon, and you wrote missable achievements 4, when you listed 5. Will let you know more if I find more when I read the rest of the achievements

It looks better, plays the same as the old PS2 version, it's a very easy 1000compared to other Dragonball titles on the Xbox. What more do you want?

The level you see on the list is the opponent's level. It
doesn't matter what your character's level is or which
character you fight as, but remember, the chance of
them breaking in is still RANDOM.

i know that, thats what your guide says in the first place but the 3 dots with super vegeta will only appear if you are finished gokus AND vegetas DU once, then cooler will be there on gokus second play.

i just did gokus 2 times in a row and no super vegeta nor cooler, beat it with vegeta (got the achievement only the after the second run) and again with goku and he was there.

so being on gokus 2nd run of DU without having finished vegeta at least once will not trigger the cooler event.

Thank you for a nice quide. Only suggestion is that for Budokai 3's tourneys that perhaps you include the Omega Shenron strategy? I read it in a thread and someone mentioned simply using his World Wind Spin attack and on my first try with him I demolished it. A big thank you to whoever mentioned it in the various "How do I beat X tournament" thread because I kept getting so close in match 5 only to taste bitter defeat.

Oh and the hell with trying to get Piccolo to break in. Nearly 30 matches and 2 levels over what was mentioned in the guide. he just did not want to play. =P

Broly:
1) Finish Goku's DU story mode.
2) Start Goku's DU again and get to the Majin Saga.

6) The red dot '???' on the left is Kabitoshin, talk to him.
7) Almost at the same spot you will find another '???' that is Tien, check him out too.8) Now fight Super Buu. Make sure you kick his butt.9) Now a new red dot will appear and Vegeta will hold off Buu so you can check it out.10) The red dot is Broly. Defeat him to unlock him.

Omega Shenron:
1) Be on Goku's second playthrough of DU.
2) Get Goku's SSJ4 capsule, it's on one of the islands near the World Tournament. After you have beaten Buu with spirit bomb and the story continues.

Some additional info and changes I would make to made this easier to understand but overally a great guide, well done!

Appreciate your guide, dude. Finished the 1k today, with the only real issue for me being Piccolo not wanting to break in. I had maybe a total of 2 break-ins last night when I played, and when I rebooted it up today, I had maybe 7 break-ins in the span of half an hour, and Piccolo finally decided to show up. I even had back-to-back break-ins against Dabura.

The Dragon Arena is an 'arena' in which you can fight enemies which get progressively stronger.
It automatically unlocks after completing Dragon Universe with all 11 characters.

I've just unlocked Uub on my 1st playthrough with Goku, so I think you can update the guide sayin it's not mandatory to be in the second one.
